FASTENING DEVICE FOR WEIGHT-CORDS.

Specification of Letters Patent.

Patented Nov. 26, 1912.

Application filed March 23, 1912. Serial No. 685,881.

To all whom it may concern:

Be it known that I, THoMAs M. HoUsn, a citizen of the United States,residing at tichmond, in the county of Henrico and State of Virginia,have invented certain new and useful Improvements in Fastening Devicesfor Weight-Cords, of which the fol lowing is a specification, referencebeing had to the accompanying drawings.

This invention relates to a simple and novel device for fastening weightcords to window sashes and has for its object to provide a device forthis purpose which may be stamped by means of a suitable die from asingle piece of metal, can be easily and quickly secured to the sash andwill at all times effectually hold the end of the weight cord inconnection therewith.

A further object of the invention is to provide a plate adapted to befitted into an opening or recess in the sash stile, said plate having anopen slot to receive the weight cord and lugs between which the knot of.

the cord is disposed, said plate being further provided with a spur oneither side of the cord receiving slot to be embedded in the sash stile,and an angularly disposed foot to be secured by means of a suitablefastening screw to the sash.

With the above and other objects in view, the invention consists of thenovel features of construction, combination and arrangement of partshereinafter fully described and claimed, and illustrated in theaccompanying drawings, in which Figure 1 is a vertical fragmentarysection of a sash stile showing my improved cord attaching means appliedthereto; Fig. 2 is a section taken on the line 22 of Fig. 1; and Fig. 3is a detail perspective view of the fastening plate.

Referring in detail to the drawing 5 designates the stile of a windowsash, 6 the guide pulley for the weight cord 7 and 8 the sash weightsecured to one end of said cord. The stile 5 is provided with alongitudinal groove or channel 9 to receive the other end of said weightcord, and at one end of said channel a comparatively deep hole or recess10 of rectangular form is provided.

My improved fastening device for the weight cord as shown in Fig. 3 ofthe drawing consists of a single metal plate generally designated by thenumeral 11. This plate in blank is of a substantially diamondshaped formin plan, and one end or point of this diamond-shaped plate is bent atright angles as shown at 12 to provide a foot which rests upon one wallof the recess or opening 10 in the sash stile. At the bend of the platewhereby the foot is provided the same is formed with an opening 13 toreceive a suitable fastening screw 14 which extends downwardly andinwardly into the sash stile. The other end of the diamond-shaped plate11 is provided with a longitudinally extending slot 15 which is open atits outer end, the inner end of said slot being enlarged as indicated at16. At the open end of the slot the offset spurs 17 are formed upon theplate 11, the opposed edges of said spurs providing a flared entranceinto the slot 15. Lugs 18 are centrally formed upon the longitudinaledges of the plate 11 and extend at right angles thereto.

In applying the device for the attachment of the weight cord to the sashstile, a knot is formed in the end of the cord 7 as clearly shown inFigs. 1 and 2, and the weight cord is then inserted into the slot 15 ofthe fastening plate into the enlarged inner end thereof. The knot uponthe end of the cord is disposed between the lugs 18 on the plate and theplate is now inserted into the opening 10 of the sash stile, the spurs17 being forced upwardly into the stile, and the foot 12 simultaneouslymoved inwardly into engagement with the opposite wall of the opening 10until the fastening plate is disposed in said opening in a substantiallyvertical position. The screw 14 is now inserted and driven into thestile to rigidly secure the plate in position. When thus disposed, itwill be observed that the knot on the end of the cord is positionedbetween the base wall of the opening 10 and the inner face of the plate11.

By means of my improved fastening device as above described, it will bereadily seen that the end of the cord is securely held in position inthe opening 10 of the sash stile while at the same time the cord can beeasily and quickly removed in the event that the same becomes broken oris otherwise unfit for further use and it is necessary to replace thesame with a new cord.

As the device consists of but a single sheet of metal, it will beobvious that the same may be manufactured at very small cost, and

is also strong, durable and eflicient in prac-v Having thus describedthe invention what i is claimed is 1. The combination with the sashstile having an opening therein, of a cord fastening plate having alongitudinal open ended slot to receive the cord and spurs on eitherside of the slot to be embedded in the stile, said cord having a knot onits end, and angularly disposed lugs formed on the plate and disposed onopposite sides of the cord knot.

2. The combination with the sash stile having a cord receiving recesstherein, of a fastening plate for the cord provided with a longitudinalopen ended slot having a flared entrance, a contracted intermediateportion and an enlarged inner end to receive the cord, saidcord beingprovided with a knot upon its end, and lugs formed on the plate andextending at right angles to the body thereof disposed upon oppositesides of the knot, a right angularly extending foot formed upon one endof'the plate and having an opening therein to receive a fastening screwwhereby the same is secured to the sash stile.

3. As an improved article of manufacture, a fastening device for sashweight cords consisting of a metal plate having a longitudinallyextending open ended slot enlarged at its inner end to receive the cordand provided with offset spurs at the outer end of said slot, theopposed edges of the spurs forming a flared entrance to the slot, lugsformed upon the longitudinal edges of the plate and extending at rightangles thereto between which the cord knot is adapted to be disposed,and a right angularly disposed attaching foot formed on one end of theplate provided with a screw receiving opening for the attachment of thesame to a sash stile.

In testimony whereof I hereunto affix my signature in the presence oftwo witnesses.
